The handles can be mounted to any pipe that is about 7/8" in diameter. I was inspired by 1up and made a Tron joystick using the plastic sides, a perfect 360 and a 1/2 PVC pipe. PVC is great because it is very easy to tap out the holes for the metric security socket cap bolts that are typically used. I made the PVC version as a template and had planned on building the final version with metal conduit; however, the PVC worked so well that metal was not necessary.
